TCT-575 Combined near-infrared spectroscopy and intravascular ultrasound (NIRS-IVUS) coronary imaging as a means to improve prediction of events by IVUS plaque burden alone

Previous clinical studies have shown that plaque burden (PB) >70%, as measured by intravascular ultrasound (IVUS), is predictive of future coronary events. But because IVUS tracing of PB is time-consuming, results from PROSPECT I did not significantly alter clinical practice. In addition to PB, the
